Lecture 72: Larynx - True False
True False Questions (Dr. McGinn by Dr. Evey)
1. The cricoid cartilage is compared to a signet ring.
2. The thyroid cartilage sits on the first tracheal ring.
3. The cricoid cartilage extends inferior to the 3rd tracheal ring.
4. The arytenoid cartilages have vocal and muscular processes.
5. The cricoarytenoid joint is a synovial joint.
6. The laryngeal prominence is unique to the male.
7. The female vocal fold is 60% longer than in the male.
8. The superior free edge of the quadrangular membrane is the thyroepiglottic fold.
9. The superior border of the conus elasticus is continuous with the true vocal fold.
10. The vestibular fold is at the inferior margin of the quadrangular membrane.
11. The lateral cricoarytenoid muscle abducts the true vocal cord and the posterior cricoarytenoid abducts the false vocal cord.
12. The thyroarytenoid muscle is immediately related to the vestibular fold.
13. The cricoarytenoid muscle shortens the vocal cord to achieve a raise in the pitch of the voice.
14. A lesion of the external laryngeal nerves is expected to cause adduction of the vocal cords.
15. The strap muscles are innervated by the ansa subclavia.
16. The larynx moves inferior during a swallow.
17. The saccule is a diverticulum of the ventricle.
18. The aryepiglottic fold contributes a medial border of the piriform recess.
19. The aryepiglottic fold is continuous with the thyroarytenoid fold.
20. Vibration of the vocal fold is mostly by the mucosa.
21. Closure of the glottis occurs by action of both the true and false focal cords.
22. The epiglottis moves anterior during swallowing.
23. Relaxation of the cricopharyngeus lowers the pitch of the voice.
24. The recurrent laryngeal nerve innervates the intrinsic muscles of the larynx with the exception of the geniohyoid muscle.
25. The recurrent laryngeal nerve continues superior the first tracheal ring as the internal laryngeal nerve.
26. The recurrent nerve is at risk in the tracheoesophageal groove during thyroid surgery.
27. The inferior thyroid artery passes into the larynx through the thyrohyoid membrane.
28. A Pancoast tumor may eventually erode the vagus, phrenic, and recurrent laryngeal nerves as well as the sympathetic trunk.
29. The false vocal fold is superior to the true vocal fold.
30. The interarytenoid muscle and the lateral cricoarytenoid muscle are synergistic in closing the larynx.
31. Lesions of both recurrent laryngeal nerves cause the vocal folds to be abducted.
32. The cough reflex is mediated by GVA fibers within the cervical plexus.
33. The external laryngeal nerve carries SVE fibers to cricothyroideus and possibly to cricopharyngeus.
34. The piriform recesses extend inferior to the region of the upper esophageal sphincter.
35. The recurrent laryngeal nerves lie in the tracheoesophageal groove and passes the anterior surface of the thyroid gland.
36. The thyroid hyoid membrane is "pierced" by the internal laryngeal artery and the superior laryngeal nerve.
37. The muscular process of the arytenoid cartilage is anterior and lateral to the posterior cricoarytenoideus.
38. The vocal process of the arytenoid cartilage is at the superior edge of the conus elasticus.
39. The false vocal fold is at the inferior edge of the conus elasticus.
40. The vestibule and saccule are apt to enlarge if you are a professional tuba player.
